State of the Arctic Report
SOA Table of Contents• Atmosphere
– Circulation– Surface temperatures– Forcing of changes
• Ocean– Circulation– Heat and freshwater content– Sea level
• Sea Ice Cover– Extent and thickness– Surface conditions
• Land– Vegetation– Water and ice– permafrost
Next SOA Topics
• Atmosphere• Ocean• Sea ice• Land• Greenland ice sheet• BiologyA new format will be used - a simple “report card”
with back-up science papers.
Arctic Climate Observations
• The SOA report reinforces that the Arctic has to be considered as a system
• The Arctic Research Program from its inception has included ocean, ice, atmosphere and marine ecology as its main elements and continues to work in this way
Current Activities
• Arctic Atmospheric Observing Network• Arctic Change Detection and System
Analysis• RUSALCA• North Pacific Climate Regimes and
Ecosystem Productivity • Arctic Sea Ice Thickness Observing

International Arctic Systems for Observing the Atmosphere
Science Goals
• Provide multi-decadal cloud, radiation, aerosol, meteorological and flux data
• Use observations to understand atmospheric and surface processes at regional scale
• Apply data to improve model parameterizations• Support calibration, algorithm development and
validation for satellite observations• Serve as logistics base for diverse science
observations, e.g., permafrost borehole, etc
RUSALCA
USA RUSSIA• Observations where
Arctic sea ice is reducing rapidly
• Bering St. fresh water, nutrient fluxes
• Regional physics and ecosystem response to change.
• Improve international Arctic science collaboration
• Explore the unknown Arctic with OE
Russian American Long-term Census of the Arctic
RUSALCA Goals:
A RUSALCA Goal: Gateway Fluxes via Long-term Moorings in Bering Strait
NOAA, NSF, RASwill install 8MooringsAcross theBering Strait in2007

• Fish community correlates reasonably well with water masses
• Fish community also correlates positively with substrate type

Climate Change Scenarios in Eastern Chukchi SeaClimate Change Scenarios in Eastern Chukchi Sea
Increase in ACW conditions (fresher, warmer, less productive)
• Less infauna, reduction of biomass hotspot
• Probably unchanged epifauna ?
• Re-distribution of fishes (expansion of south-central Chukchi fish)
• Invasion of invertebrates and fishes from Bering Sea
• Longer food chains (less tight benthic-pelagic coupling)

Partnerships for Sustained Observations
Arctic Observing Network
• Interagency, international effort to observe over decades, changes in the environment in the Arctic to provide stakeholders with climate, weather, research and resource information critical for the global society.
Goal: ContributeTo the designOf an ArcticObserving NetworkBased on the SEARCHImplementation Plan and Existing Operational Networks
Developing International Science Partnerships
• IPY
• Arctic Regional GOOS
• Arctic Observing Network (AON) and its developing international counterpart
• Arctic GEOSS

International Polar Year
International Polar Year: Exploration-Observations
RUSALCA: Exploration of Marine Life in the Pacific-Arctic: What lives in this part of the Arctic Ocean? How will it migrate due to climate change?
International Polar Year: Arctic Observations
• Causes and Impacts of Recent Changes in the Pacific Arctic (RUSALCA)
• Polar Atmospheric Observatories and Field Campaigns (IASOA)
• Polar Stratospheric Ozone Depletion Observations
• Autonomous under-ice systems testing (AGAVE expedition, methane fluxes from the seafloor)
• Unmanned Aircraft Systems (UAS)

Value to Society
Possible Arctic Influences on Global Climate Change:
• Increase of methane in the atmosphere due to a thaw in the permafrost on land and under water
• Fresh water /salt water unbalances, Ocean circulation disruption
• Changing albedo of the planet due to melting of sea ice and taller vegetation
• Extinction or migration of many species
• Rising sea level due to the melting of the Greenland Ice Sheet
• Increase in severe weather 26
Changes in sea ice coverChange in planetary albedo
Melting permafrostrelease of greenhouse
sequestered gases
Melting Greenland ice sheet – Rises in sea level
Atmospheric Influences on the total system are profound
